One-Pot Synthesis of 4-Substituted 1<i>H</i>-[1,2,3]triazolo[4,5-<i>c</i>]quinolines Through CuO-Promoted Tandem Cyclization Reactions of (<i>E</i>)-3-(2-Bromoaryl)-1-arylprop-2-en-1-ones with Sodium Azide
A facile and efficient protocol for the synthesis of 4-substituted-1H-[1,2,3]triazolo[4,5-c]quinolinesthrough a CuO-promotedtandemcyclizationreaction has been developed. This method allows for the construction of two heterocyclic rings in a one-potreaction of readily available (E)-3-(2-bromoaryl)-1-arylprop-2-en-1-ones and sodiumazide without the addition of any additive. A series of triazole-fused
